vader:How did the driver know Grace would step out in front of the vehicle and the driver pulled over. If Matthew hired someone, he'd have gone for a proper hitman and not some two bit lorry driver. Think.
Ooooh it's getting good now all this heated debate!
Come on Vader stay with us you know he did it!!
Think.......... they are walking one way, to the cop shop, one road to cross, only one way to go.
His phone goes, he answers it and stops walking, she wants him to turn himself in, so when he stops walking with her she turns around and then not looking at the road, Oh no Grace watch that truck, too late she is dog meat!
It was a chance thing a last ditch attempt before they got to the cop shop, hiring a hit man (by that I take it you mean to have her shot in the street?) that is more suspect, a hit and run looks more random, could have been anyone stepping out in front of a lorry. Having somebody shot, it's meant for that person, too many questions get asked, this way it's taken as an accident that the driver then bricked it and drove off, ergo Matty gets away with it........ for now at least!
Top and bottom of it is this, it is a soap, don't think it can stand up to massive scrutiny, you just have to watch TV Burp to see the holes all over them, it written quick and churned out sausage style.
Come on Vader you want him to get his comeuppance, well here it is!
